• The module Art. 4681 / Art. 1621VC operates by default as a main external unit (timed busy signal). To set it as a secondary
external unit (busy signal active for the whole time the riser is in use), set all the selector DIP switches to ON.
• When a call is transmitted from the external unit, if a busy tone is heard instead of the ringtone, this means communication
with another external unit is in progress.
